MYERS, OF NEW YORK, N. Y., ASSIG-NOR TO ICE CREAM SMACK PRODUCTS 00., A CORPORATION OF OREGON ARTICLE DISCHAR GING AND CONVEYING APPARATUS FOR PAPER-CYLINDER- FORMING MACHINES Application filed December 31, 1927. Serial No. 243,878.

My present invention relates tomachines for manufacturing cylindrical cups from continuous strips of paper. In such machines there is provided, in general, a holder for a roll of paper strip, a rotary mandril on which the cup is formed, a feeding means to convey the paper from the holder to the mandril, a means to detach from the strip definite lengths of paper for winding on the mandril, a means to turn over and press in an edge of the paper on the mandril to form a bottom to the cup, and an ejector mechanism to remove the finished cups from the mandril, together with means for receiving the finished cup, removing it from the ejector and discharging it from the machine.

My present invention has for an object to provide an improved apparatus for removing the ejected cup from the ejector and delivering it into a suitable receptacle on an oflt'take conveyor. 7

Further it is an object of the invention to provide a device in the nature of a tongs to grip or hold the cup delivered to it by the ejector until the ejector has been withdrawn and the gripping action released, whereupon the device will drop the cup into the receptacles of a passing conveyor.

Further it is an object to provide a device for the purposes specified of a very simple, effective and rugged construction that will stand continued usage for an indefinite time and one which will not deform or otherwise injure the cups.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends the invention resides in those novel details of construction, combination and arrangement of parts, all of which will be first fully described and then be specifically pointed out in the appended claims, reference being had to the accompanying drawing, in which:

Figure 1 is a plan View of a machine embodying my invention.

Figure 2 is a side elevation of the machine.

Figure 3 is a vertical cross section taken on the line 3-3 of Figure 1, showing the tongs in position to receive a finished cup.

dril, 5 the ejector, 6 the paper edge turn-overfinger and 7 the paper bottom-forming presser member, all of which parts may be of 3 a well known construction and, per se, do not constitute a part of the present invention.

My invention resides in the provision of a cup receiving tongs carrying shaft 8 oper ated at proper times by means of the operating mechanism 9.

On the shaft 8 is a tongs mounting body 10 to which a split arm 11 is pivoted, the sections of'the arm being pivoted at 12. The arms sections have opposed semi-cylindrical receiving recesses 13 into which the finished cup is delivered by the ejector 5 when the tongs are in the position shown in Figures 8 and'4.,

In order to hold the sections of the arm 11 closed together I provide a tension screw and nut device 14 with a tension spring 15,. By adjusting the screw the degree of tension tending to hold the sections of the tongs arm together may be variedat will.

The tongs arm sections are provided with opposed recesses 16 to receive a splitter 17 (wedge member) when the tongs shaft 8 is turned to bring the tongs into engagement with the splitter, thereby separating the sections of the arm 11 and releasing the finished article into a receiving cup 19 of an oiftake conveyor 18, the travel of the conveyor being so timed that a receiving cup will come into position to receive the conveyed article at the time it is released from the tongs.

In operation at the time the ejector is about to function the tongs are in the vertical position adjacent to the mandril, as shown in Figures 3 and 4. Immediately upon receiving the cup from the ejector the tongs are swung downwardly until they engage the splitter 17 whereupon the cup is released from the tongs and drops into the receptacle 19 of the offtake conveyor, which receptacle has, in the meantime, come beneath the place where the tongs let go. This operation is repeated so long as the machine is running. See Figures 3, l, 5 and 6.

Any mechanism desired may be provided for rocking the shaft 8 at proper intervals and any desired mechanism may be provided for operating the ofitake conveyor. As mechanisms for these purposes are well known further description thereof is thought to be unnecessary.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the novel details of con struction, manner of use and the advantages of my invention will be readily understood by those skilled in the art to which the invention relates.

What I claim is:

1. In cylinder forming machines the combination with a forming mandril and an ejector, of a pivoted stationarily located receiving element into which said ejector delivers the articles from the mandril, means to move said receiving element on its pivot from a receiving to a discharging position, and means at the discharging position to release the article from said receiving element.

2. In cylinder forming machines the combination with a forming mandril and an ejector, of a receiving element into which said ejector delivers the articles from the mandril, means to move said receiving element from a receiving to a discharging position, means at the discharging position to release the article from said receiving element. and an ofitake conveyor having receptacles for the articles released by said receiving element.

3. In a cylinder forming machine wherein is provided a forming mandril and an ejector to remove formed articles from said mandril; the combination with the ejector, of a rela tively stationarily located tongs pivoted on a horizontal axis to receive and hold the articles ejected, means to move said tongs on its pivot from a receiving to a delivery position, means operable at the delivery position to release the articles from the tongs.

4. In a cylinder forming machine wherein is provided a forming mandril and an ejector to remove formed articles from said mandril; the combination with the ejector, of a pivoted tongs to receive and hold the articles ejected, means to move said tongs from a re ceiving to a delivery position, means operable at the delivery position to release the articles from the tongs, and an offtake conveyor to receive the articles released from the tongs.

5. In a cylinder forming machine wherein is provided a forming mandril and an ejector to remove formed articles from said mandril;

the combination with the ejector, of a relatively stationarily located tongs pivoted on a horizontal axis to receive and hold the articles ejected, means to move said tongs on its pivot from a receiving to a delivery position, means operable at the delivery position to release the articles from the tongs, said tongs comprising a swinging body, a split arm, the sections of which are pivoted to said body, spring tension means to hold said sections together. said arm having an article receiving opening.

6. In a cylinder forming machine wherein is provided a forming mandril and an ejector to remove formed articles from said mandril; the combination with the ejector, of a stationarily located pivoted tongs to receive and hold the articles ejected, means to move said tongs on its pivot from a receiving to a de livery position, means operable at the delivery position to release the articles from the tongs, said tongs comprising a swinging body, a split arm, the sections of which are pivoted to said body, spring tension means to hold said sections together, said arm having an. article receiving opening, and a splitter receiving opening, said releasing means comprising a splitter-wedge to enter said splitter receiving opening and separate the sections of the arm.
